ARRT PRACTICE EXAM 1 WITH
CORRECT ANSWERS 2025
Rheostat - correct answers - What type of device is the mA selector?
7; 20 - correct answers - The angle of the anode in the region of the
target has a variation of ° to °.
10 days to 6 weeks of development - correct answers - Exposure of an
embryo or fetus to radiation from can result in congenital
abnormalities.
kilovoltage - correct answers - The quality of x-ray photons is affected by:
15-20; caudad - correct answers - For a posteroanterior (PA) axial oblique
projection of the C-spine, the central ray is angled ° in
the direction.
full inspiration - correct answers - What instructions for respiration are given
to a patient during a routine chest lateral projection?
100;100 - correct answers - Selecting exposure factors of
milliampere- seconds (mAs) and peak
kilovoltage (kVp)
delivers the LEAST amount of radiation to the patient.
Thermionic emission - correct answers - The process of electrons boiling off
the filament is referred to as:
sitting eye level with the child and walking them through the
examination - correct answers - A 4-year old patient enters the
radiology suite for chest radiography and appears anxious. The child has
never had the examination before. She is not speaking or answering
questions. The technologist could
best attempt to communicate with the child by:
H2O2 - correct answers - Combining 2 hydroxyl radicals (OH*) will form:
15 inch minimum SSD - correct answers - Which of the following is a
guideline used to reduce personnel and patient dose during fixed
fluoroscopy?
, rotor and stators - correct answers - Which of the following components
make up the induction motor in an imaging system?
bregma - correct answers - The junction between the coronal and sagittal
sutures of the skull is called the:
bargaining - correct answers - A terminally ill patient has asked the
doctor about possible volunteer opportunities in the hospital. She
says that if she can volunteer in the hospital, she might be able to extend
her life a bit longer from doing
good deeds. This represents the stage of grief for the patient.
86 - correct answers - All of the following are within acceptable kVp
accuracy variance for an exposure using 80 kVp EXCEPT
FOR kVp.
-86
-84
-82
-76
visceral - correct answers - The kVp variance is within + 5%. At 80 kVp, the
variance is 4 kVp (80 x .05 = 4). Therefore, 76 kVp - 84
kVp is within acceptable limits.
1,2, and 3 - correct answers - According to the American College of
Radiology, which of the following are indications for obtaining a
skeletal survey? 1. suspected nonaccidental trauma 2. skeletal dysplasias,
syndromes, and metabolic
disorders 3. neoplasms
low contrast - correct answers - An image that has many shades of
gray with few differences among them is defined as exhibiting:
bone - correct answers - Of the following, the greatest attenuator of x-
rays is:
-bone
-air
-muscle
-fat
2 inches above the iliac crests - correct answers - For an upright abdomen,
the central ray should be placed on the midsagittal plane and:
kVp - correct answers - All of the following affect the spatial resolution
of an image EXCEPT FOR:
-kVp
-part size
